Three masses are located in the x- y plane as follows: a mass of 6 kg is at (0 m, 0 m), a mass of 4 kg is at (3 m, 0 m), and a m
enot [183]

Answer:

The center of mass of three mass in the x-y plane is located at (1,0.5).                  

Explanation:

It is given that, a mass of 6 kg is at (0,0), a mass of 4 kg is at (3,0), and a mass of 2 kg is at (0,3). We need to find the center of mass of the system. Center of mass in x direction  is :

C_x=\dfrac{6\times 0+4\times 3+2\times 0}{6+4+2}\\\\C_x=1

The center of mass in y direction is :

C_y=\dfrac{6\times 0+4\times 0+2\times 3}{6+4+2}\\\\C_y=0.5

So, the center of mass of three mass in the x-y plane is located at (1,0.5).

You will now use Graphical Analysis to calculate the slope of the line. Choose Analyze from the menu. Select Automatic Curve Fit
Mars2501 [29]

Unfortunately, to obtain the numerical value of the slope of the line using the given formula, 2 points must be given. Because of the lack of the given points however, let us just go through why the formula is like that. The given formula stated is: slope, m = (y2 - y1) / (x2 - x1). That is merely a two-point representation of the slope's definition, which is "rise over run".

If a spring has a natural length of 5 cm and a force of 30 n is required to maintain the spring stretched to a length of 9 cm, f
devlian [24]
F = k*d, k = F/d.

Force = spring constant * distance.

F = 40, d = (9-5)/100 = 0.04m (extension in metres).

k = 30 / 0.04 = 750.
